| dc.description.abstract | This project report outlines the research, design and implementation of a low power direct current (DC) to alternating current (AC) inverter with particular focus on developing a low cost transformer-less voltage source conversion that has a higher efficiency as well as compact in size. The stand alone PV system design also incorporates an MPPT algorithm to ensure maximum transfer of power. The final design consists of a two-stage converter consisting of a DC-DC Step Up stage and a DC-AC Inverter stage. The DC-DC Step up converter was based on switched capacitor techniques To achieve this improvement in inverter efficiency and a reduction in cost, the power transformer and magnetic components such as inductors have been eliminated. In addition, inverter voltage control techniques such as pulse width modulation (PWM) and switching of MOSFETs have been optimized through digital control using microcontroller unit. The concern for environmental degradation from fossils fuel as well as well as the depletion of these resources has led to major investment in the research and development of the renewable energy sources. Solar energy has emerged as one of the major alternative source. The disadvantages of using solar energy are its higher capital cost in comparison to that of conventional sources of energy, and its conversion efficiency, which in commercially available Photovoltaic (PV) systems is less than 90%. Consequently, for utility connected PV generation to become a viable alternative energy source, its efficiency needs to be improved, its cost reduced, and the quality of power supplied by the inverters must meet standards. Therefore, this project seeks to achieve this improvement as outlined in the report and the MPPT technology helps in achieving this. | en_US |
